McGarrity, J., & Sayre, F. B. (1939). Letter from Joseph McGarrity to Francis Bowes Sayre, thanking him for his courteous reply and clarifying what he meant in a previous letter by "National entity" and the differences between what a country that is a "National entity" can do such as issue passports and a country that is not, and as such Ireland cannot be considered a "National entity".
